The best surfaces for reflecting light are very smooth, such as a glass mirror or polished metal , although almost all surfaces will reflect light to some degree. Reflection of Light When light waves are incident on a smooth, flat surface, they reflect away from the surface at the same angle as they arrive.

Which metal reflects light the best?
A polished silver surface , for example, reflects about 93 percent of the incident visible light, which is very good as metals go. Interestingly, if the metal layer is very thin–only a few hundred atoms thick–then much of the light leaks through the metal and comes out the back.
Which side of aluminum foil reflects light?
The shiny side of aluminum foil reflects more light than the dull side. This is because the shiny side is a smoother surface than the dull side,...
Can you use tin foil to reflect light?
Aluminum foil can be place on the grow room’s walls and laid under the room’s plants to reflect light . Hang aluminum foil with its shiny side outward instead of against the wall. The foil doesn’t reflect as much light as white paint or grow films, but the amount of light reflected should improve plant growth.
Why do mirrors reflect light so well?
Mirrors reflect mainly because they are electrically conductive . Light is an electromagnetic field, and when it hits a mirror the metal inside of it (usually aluminum or silver) cancels out the electric field parallel to the mirror which causes it to change directions and reflect away.
What metal is shiny?
Many different kinds of metal are shiny. Gold is a metal which stays shiny for a long time because it does not react much chemically with the air. Silver is shinier, but tarnishes easily. Many other metals, like iron or steel, aluminum, and copper are also shiny.
Which is the most reflective metal?
The most reflective metals in the world are silver and aluminum . Reflective aluminum or “lighting sheet” has a mirror like surface and is made from high purity aluminum with specific photometric qualities to control light.

What reflects light better white or silver?
Silver reflects much more light , so you’ll use silver when you position the reflector back away from your subject. If you need to get a reflector right up close, then use white, because it doesn’t reflect nearly as much light as silver.
Does aluminum foil absorb or reflect heat?
The surface of aluminum has the ability NOT TO ABSORB , but TO REFLECT 95% of the infrared rays which strike it. Since aluminum foil has such a low mass to air ratio, very little conduction can take place, particularly when only 5% of the rays are absorbed.
Why do people put tin foil over windows?
Aluminum foil keeps out odor, moisture, germs, oxygen, and light , which could contaminate food. ... Aluminum foil on windows is most effective at keeping out heat and light when you place it shiny side out and cover its backside with a layer of something else, like insulation or cardboard.
Does a mirror show how others see you?
